The genotype and phenotype ratio for the first cross will be 100% Rr and 100% round seeded while that of the second cross will be 1RR:1Rr and 50/50 round/wrinkle seeded offspring respectively.
Genotype and phenotype ratio
For the first cross:
             RR  x  rr
           Rr  Rr  Rr  Rr
Genotype ratio: 100% Rr
Phenotype ratio - 100% round seeded
For the second cross:
            RR   x   Rr
           RR  Rr  RR  Rr
Genotype ratio: 1RR:1Rr
Phenotype ratio = 50% round seeded and 50% wrinkle seeded.
